Objective To investigate the concentration of procalcitonin,C-reactive protein and WBC count for patients with dif-ferent kind of bacterial infection.Methods 49 blood samples and 81 other samples were collected form different patients for bacteri-al culture.Meanwhile,procalcitonin,C-reactive protein concentration and WBC count of those patients were determined to find whether these indicators exhibited any difference between Gram-positive and Gram-negative bacteria infected patients.Results For bloodstream infection,PCT levels in patients with Gram-nagetive bacterial infection were obviously higher than those with Gram-positive infection(P <0.05 ).For other infection,there was no statistical difference among patients′PCT,CRP concentration and WBC count(P >0.05).Conclusion PCT concentration is valuable in the differential diagnosis of blood stream infection caused by Gram-negative and Gram-positive bacteria,but not in local infection infection.

There are approximately 240 million patients with chronic hepatitis B virus (HBV) in the world.Despite the production of HBV vaccines and antiviral drugs, HBV still remains a serious threat as an infectious disease to human health.Due to the lack of an ideal animal model, the study of HBV is limited.This review was to analyze in accordance with existing HBV animal model, to explore the differences in applications of various models regarding their etiology, pathology and pathophysiology.thus, to provide a reference for researchers in future HBV research to better use the resources.

The medical law science interdisciplinary talents play an crucial role in solving medical service dispute and alleviating contradictory. Based on the questionnaire survey and the interview to the court and law offices as well as the analysis of the society's demand for the knowledge structure and ability of medicine law professionals, we proposed the construction of the training mode for medicine law professionals with the ability to adapt to the social demand.

The main purpose of ideology and morality course is not only to pass on knowledge and theory to students but also to teach them ideology and conduct norms on the basis of knowledge and theory. The reform and exploration of teaching patterns of ideology and morality course should concentrate upon the three ways of "theory teaching, case analysis and classroom discussion", so that teachers and students can interact and cooperate with each other, serve the same teaching theme and bring into fullplay teachers' leading function and students' initiative in classroom teaching.

Objective To investigate the distribution and antimicrobial resistance of clinical bacterial strains isolated from the cervical secretions of parturient women .Methods A total of 239 bacterial strains were isolated from 1 519 cervical specimens of parturient women .These strains were identified and tested by Kirby‐Bauer method for their susceptibility to antimicrobial agents .Results Escherichia coli was the most frequently isolated bacteria ,accounting for 34 .3% .The bacterial strains were more or less resistant to commonly used antimicrobial agents .Conclusions Various bacterial species are identified in the cervical secretions of parturient women ,primarily Escherichia coli and Staphylococcus aureus .Bacterial culture and antimicrobial susceptibility testing are important for clinicians to take appropriate measures to reduce the incidence of mother‐to‐child infections .

Abstract: Objective　To investigate the composition and diversity of midgut microbial community of Haemaphysalis longicornis infected with severe fever with thrombocytopenia syndrome virus (SFTSV)． Methods　The midgut DNA of three group Haemaphysalis longicornis infected with SFTSV was extracted, and the 16S rDNA gene of the sample was sequenced by HiSeq platform. The composition and diversity of endosymbiotic microbial community were clarified by OTU cluster analysis and alpha diversity analysis. Results　The midgut microbial clusters of the three groups infected with SFTSV were 143, 113, 163 OTUs respectively; the sparsity curve and abundance grade curve showed that the data had sufficient sequencing depth, and the midgut of Haemaphysalis longicornis infected with SFTSV was rich in microbial composition, but the species distribution was uneven. The analysis of microbial community composition showed that Proteobacteria, Firmicutes and Actinobacteria were the main dominant bacteria at the phyla level. At the class level, Gammaproteobacteria, Bacilli, Betaproteobacteria and Actinomycetia were the main dominant bacteria. At the order level, Legionellales, Bacillales, Burkholderiales and Actinomycetales were the main dominant orders. At the family level, Coxiellaceae, Bacillaceae, Moraxellaceae and Rhodococcaceae were the main dominant families. At the genus level, the relative abundance of Coxiella was the highest, followed by Aeribaillus and Azonexus. Alpha diversity analysis showed that the average Shannon index was 139.67, the average Simpson index was 0.48, the average Chao index was 145.06, and the average ACE index was 147.11. Conclusions　The species diversity of intestinal microorganisms in Haemaphysalis longicornis infected with SFTSV is rich. The results provide a basis for further exploring the interaction between intestinal microbes of Haemaphysalis longicornis and SFTSV and developing new ideas for the prevention and control of ticks and tick-borne diseases.

Objective:To investigate the mechanism of liver and lung injury in mouse septic models.Methods:Twenty-four male Kunming mice were subjected to cecal ligation and puncture(CLP)or sham operation.The permeability of microvasculature,water contents,activities of myeloperoxidase(MPO)and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation.Results:Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group.MPO activity and water content in CLP group were obviously higher than those in the sham operation group.The apoptosis of lung microvascular endothelial cells at 12 h in CLP group(5.03?0.92)% was significantly higher than that of control group(3.48?1.21)%(P

Objective To investigate the feasibility of low dose dual phase contrast-enhanced chest CT with iterative mod el reconstruction (IMR) technique.Methods Totally 130 patients with suspected pulmonary occupying lesions underwent dual phase contrast-enhanced chest CT,who were randomly assigned into 2 groups (group A and group B,each n=65).Patients in group A were scanned with 100 kV,DoseRight technique with dose right index 10,and images were reconstructed with the hybrid iterative reconstruction (iDose4).While patients in group B were scanned with 80 kV,DoseRight technique with dose right index 8,and images were reconstructed with iterative model reconstruction (IMR).The objective image quality,subjective image scores and the excellence rate of vascular visualization were compared in both pulmonary artery (PA) and bronchial artery (BA) phases.The radiation dose was also calculated.Results The effective dose was (3.30 ±0.89)mSv in group A and (1.27 ±0.19)mSv in group B.Compared to group A,the effective dose reduced 61.52％ in group B (P＜0.001).Lower image noise and greater CNR were obtained in group B compared to group A in both PA and BA phases (all P＜0.001).No significant difference was found in subjective image scores of lung and mediastinal setting and the excellence rate of vascular visualization in both groups (all P＞0.05).Conclusion Using IMR,dual phase contrast-enhanced chest CT allows for a radiation dose reduction up to 61.52％,meanwhile,ensures the image quality and meets the diagnostic requirements.
